The John Popper [ tickets ] Band, a side project assembled by Blues Traveler's frontman, has postponed the first two dates of its club tour in support of the forthcoming album "Zygote." The tour was originally set to begin Sept. 1 and 2 with concerts in Delaware and Connecticut, but will instead open Sept. 6 in Syracuse, N.Y.

No reason for the postponement was immediately given, and Popper's management wasn't available for comment on Monday afternoon (8/30). It's expected that the canceled shows at the Bottle and Cork in Dewey Beach, Del., and at Toad's Place in New Haven, Conn., will be rescheduled.

Meanwhile, the cause of death of Popper's Blues Traveler bandmate Bobby Sheehan, who was found dead in his New Orleans apartment on Aug. 20, still has not been reported by the New Orleans Parish coroner's office. According to an office spokesperson, the results of toxicology tests from Sheehan's autopsy have been delayed indefinitely due to a departmental backlog.

Outside of a benefit performance at the Warfield Theatre in San Francisco on June 28th, Blues Traveler took a break from touring in 1999. The band was to follow that show with performances July 3rd and 4th at the Denver-area Red Rocks Amphitheatre, but the shows were cancelled after Popper was admitted to a California hospital complaining of chest pains. Popper then underwent angioplasty surgery to clear a blocked artery.
